Product Overview Looking for a clean way to lower the front of your NBS truck without compromising ride quality? QA1’s 2" drop spindles are a simple, effective solution for achieving a lower stance while preserving suspension geometry and steering performance. Designed specifically for 2WD 1999–2006 Silverado 1500 trucks, these spindles work seamlessly with QA1 coil-overs and control arms. CLEAN, CONSISTENT FRONT DROPThese spindles deliver a true 2" front drop by lowering your truck at the spindle instead of changing spring height. That means your suspension travel and steering geometry stay intact—giving you the stance you want without the harsh ride or alignment headaches. COMPATIBLE WITH FACTORY OR QA1 CONTROL ARMS These spindles are engineered to work with OEM control arms or QA1’s tubular upper and lower arms—giving you flexibility whether you're keeping your stock setup or upgrading to a full QA1 suspension system. FITMENT NOTES Fits 1999–2006 Chevrolet Silverado / GMC Sierra 1500 2WD with coil spring front suspension: Requires 17” wheels or larger: Not compatible with vehicles originally equipped with torsion bar front suspension
